The simple explanation: HFC is a technology that will connect Australians in predominantly metro areas to the NBN. The technical explanation: HFC is short for Hybrid Fibre Coaxial, and is typically used to connect properties to the NBN where an existing pay TV (Foxtel) or cable network (Telstra or Optus) is available.
People also ask, what wavelengths are used in a conventional HFC network?
HFC networks were traditionally designed using one or two wavelengths (1310 and 1550 nm), with fiber delivered (or “fed”) to a node and coax then used to “distribute” the RF signal to the customer.
Beside above, what is a hybrid fiber optic cable?
A hybrid fiber coaxial (HFC) network is a telecommunication technology in which optical fiber cable and coaxial cable are used in different portions of a network to carry broadband content (such as video, data, and voice). 2) The higher bandwidth supports reverse paths for interactive data flowing back from the user.
What is a node in cable network?
A node is part of the Hybrid fibre-coaxial cable network. Specifically it is the part that translates between fiber and coax (light and RF) as fiber is used to extend the area that a single head end or hub can cover beyond what can be transmitted over RF on coax with amplifiers.
Which is better HFC or FTTC?
HFC uses coax cable which is a better medium than the telephone copper wires of FTTC. FTTN delivers fibre to a node, which is a small streetside cabinet in your area. Line lengths are meant to be no more than 1km, but that is still much further than FTTC, so provides the least possibilities for bandwidth.
